Spin Tuner

Oh man. I totally forgot to post here where nobody will read it about my
tuner app. I made this for myself a couple of years ago and finally polished it up just enough to put it on the App Store this spring. It’s basically just a visualizer that compares what it hears to the configured reference tones (i.e., the notes you’re tuning to) which makes it much more responsive than a pitch-detecting tuner.

It’s free, but I also added a special cosmetic-only feature as a 99 cent in-app purchase, just to see how many people would “tip” me. So far it’s paid for my annual developer membership, so that’s nice.

    Dave, downloaded your app today and I love it.

    A few questions.

    Found that if you press a spinner, the reference tone will sound. Any way to get it to stick on? (want my wind instrument students to start hearing and adjusting to the beats between their sound and the ref. Come to think of it, if you sum the ref and the input sound, we might be able to reinforce that (when using headphones.)

    Adding tunings: I couldn’t figure out how to edit tunings once I finished making them and added them to the list. Edit while you are building them is straight forward, but not after the fact. Is this possible?

    Thanks, kevin

    I’m so sorry it’s taken me so long to reply to your comment. I don’t really use that blog much at all, and I only today noticed that it had found a legitimate comment amonsgt all the spam. If you still use the app, hopefully this will help.

    I couldn’t ever get the tone generator to be as loud as I want (you’ve probably noticed this..) so I don’t advertise it as a feature. Having it stay on is a great idea–I think it would make most sense to add that to the single-note view you get when you double tap a “spinner”, put a little tuning fork icon there. I’ve been meaning to update the app for months, add a few things to make things easier/more fun, but mostly I want to try and get the note loud enough to be useful. It might be the case that the speaker on the phone just can’t produce much output at those frequencies.

    As for editing tunings, it’s not obvious at all but if you tap the Edit button on the tunings list and then tap one of the rows, it’ll return you to the edit screen for that tuning.
